A newly filed patent (Publication Number: US20240034257A1) describes an innovative audio signaling system for automated machines, such as agricultural or construction vehicles. The system includes a field audio system with a control hub and an audio output device that emits an audio action signal in response to action instruction signals. An audio control system onboard the machine captures the emitted audio signal, evaluates it to determine the action needed, and sends corresponding instructions to the automation system. The control circuit includes an audio recognition system with noise removal and frequency detection components to accurately identify the audio action signal.

Furthermore, the patent details the use of reference noise superimposed with the audio action signal for correlation purposes. The system can be applied to a variety of automated machines, with each having its own audio control system. The field audio system can be triggered remotely through a user interface or automated system events. The audio action signal can be a multi-tone or patterned signal, with the system capable of retransmitting the signal when detected. Overall, the patent showcases a sophisticated audio signaling system that enhances automation and control in various vehicle applications, providing a detailed insight into the technical components and functionalities of the system.
